## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-piece-of-advice-64bbcd5e -d '<json body>'
```

Example prompt: Give me one short, practical piece of advice about money — something concrete I can actually use — in English, and use seed 42 so I can reproduce it later.

## When to prefer this

Choose this endpoint when you need a short, practical, non-generic piece of advice on a specific topic (work, life, or money) and want reproducibility via a seed or deduplication via an ID. Ideal for advice widgets, chatbots, daily-tip features, or coaching agents that need consistent, filterable content in English or Spanish. Prefer this over generic LLM prompting when you want a cheap ($0.0025), fast, topic-scoped, deduplicated advice call with built-in reproducibility.

## Known failure modes

- Invalid or unsupported topic filter returns an error or empty result
- Unsupported language code returns an error
- Payment not included or insufficient ($0.0025 USDC required) results in 402 Payment Required
- Invalid seed value may produce unexpected behavior
- Rate limiting or service unavailability returns 5xx errors

## How this service works

60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.

## Output

Returns a single practical advice item including the advice text (short and concrete, not generic), a unique ID for deduplication, the topic it covers, the language (English or Spanish), and the seed used — allowing the caller to reproduce the same result or avoid repeats.
